Acharya Prashant explains that a truly liberated person, often referred to as a 'Gyani' or knower, is actually a non-knower who is totally free of knowledge and innocent of it. He asserts that having knowledge is ignorance, while being free of knowledge is wisdom. The liberated one acts as a spontaneous instrument of the divine, lacking free will and personal decision-making, much like a pen that does not know what it is writing. This state of surrender is not a decision but a realization of an immensity that deserves more respect than one's own limited self, leading to a state of effortless action and relaxation.
